CHECKING THE CHARGE SIGNAL

Wait until the charge signal lights on.

The charge signal can be seen both in the viewfinder and on the back of the Power Control.

SELECTING THE APERTURE

Any aperture can be used for TTL AUTO Flash photography with the OM-2, within the TTL AUTO range. Determine the F stop according to your photographic purpose.

For guidance (ASA 100) * with Telescopic Auto Tube 65.116 or Auto Bellows
By positioning the calculator panel in reverse and setting it to ‘G. No. 10’ you can read the effective aperture range at a glance. See page 23.

TAKING THE PICTURES

(Turn the aperture ring until the meter needle points to 1/30 sec. or slower, and shoot.)

CHECKING CORRECT AUTO FLASI-

If the signal light blinks repeatedly, the picture was properly exposed by flash.
*The signal light blinks repeatedly also at over-exposure, so be sure the subject distance is within the TTL AUTO range shown on the exposure table.
The correct auto flash signal can be seen both in the viewfinder and on the back of the Power Control.

SHOOTING WITHOUT FLASHLIGHT

If the signal light goes out, the picture will turn out under-ex-posed. Choose a larger aperture.

If the signal stays lit (the ring flash did not fire): The subject is bright enough and the picture was taken properly by existing light. The electronic flash was not needed. (In case exposure must be

If you want to take pictures with existing light, turn the Control Power off; the charge lamp goes out and the ring flash will not fire even when the capacitor is fully charged.
achieved by flash illumination: Turn the aperture ring until the meter needle points to 1/30 sec. or slower, and shoot.)

HANDLING CARE	BEHANDLUNGS-HINWEISE
Replace all four batteries at the same time with new batteries.	Condensation

due to sudden movement from a low to a high-temperature area can prevent the flash from firing.
|
---|---
When the flash is not to be used for a long period of time, remove the batteries to prevent leakage.| At sub-zero temperatures, the batteries will not function normally. So warm them sufficiently before use.

Leaving the switch ON shortens battery life.| If illumination bulbs burn out, have them replaced by an authorized Olympus service center. NEVER try to do it by yourself.

Do not use with flash units other than the T32 (or T20).| Have repairs performed by an authorized Olympus service center. Dismantling a flash unit involves a hazard.

As the color temperature of the ring flash is similar to that of daylight, use daylight color films.
At a working distance of over 2m (0.7 ft.) the picture edges may darken (with MC Auto Macro 135mm F4.5 and 50mm F3.5).
The ring flash can be used with ZUI KO 35mm F2.8, 50mm F1.8, 50mm F1.4, 85mm F2, 100 mm F2.8, 135mm F3.5 and 135mm F2.8 lenses. The picture edges may darken if the working distance exceeds the closeup range.
In TTL AUTO flash operation, use Accessory Shoe 3 when combining the Power Control with the OM-2 (not OM-2N). In MANUAL with the same combination, set the shutter speed at 1/30 sec. or slower.
Do not exert stronger force upon the Power Control than it needs, when it is attached to or detached from the camera.
Do not hit the flash unit and do not let it strike any hard object.
Do not leave the unit in places with temperatures over 122° F (50°C), or high humidity.
The ring flash may cause “red-eye” effect to occur in portraits.
For multiple manual flash, set each G.N switch-ing knob to ’10’.
If cleaning is necessary, wipe the units with a soft cloth only.
The Lens Pouch 150 can accommodate the T Power Control 1.
Do not overtighten the T10 (or POL) when a filter has been mounted on the lens.
The ring flash equipment does not feature ex-plosion-free construction. Never use it in the presence of flammable gas.
Da die Lichttemperatur des Ringblitzes dem Tageslicht entspricht, sind Tageslicht-Colortilme zu verwenden.

MEDICAL ZUIKO
Medical close-up and macrophotography conventionally require sophisticated and complicated techniques involving difficult exposure calculations, unwieldy equipment and undesirable directly reflected light. However, this form of photography can now be accomplished in the TTL “OTF” AUTO mode accurately and easily merely by pressing the shutter release, when Olympus ring flash equipment is used.

MAIIONAL VAIIWIESISDF MEDICAL ZUIKO

Accurate and easy autoflash exposure The OM-2’s electronic brain centrally controls all exposure data to do away with complicated cal-culations. It automatically shuts off the ring flash emission when the correct amount of light has reached the film surface.
Continuously variable magnification By sliding the Telescopic Auto Tube 65-116, changes in magnification can be monitored continuously in the viewfinder.
Convenient working distance even for high image magnifications The MC Auto Macro 135 mm lens features long working distances 37cm (14.6″)—co, enabling the photographer to take enlarged images of a lesion without interrupting surgical procedures. The MC

Auto 1:1 80 mm Macro is designed to provide optimum resolution at life-size. 4. Although the Macro 135 mm has a maximum speed of F4.5, it allows full-open aperture viewing as bright as F4 to facilitate focusing and composition. 5. Ring Filter POL With the aid of the cross polarizing filter POL, the ring flash reproduces glossy surface objects, reducing undesirable annular light reflection. 6. Hand-held functionality The compact and convenient design of the equipment ensures mobility not only for medical but also for outdoor action photography. 7. Choice of power sources The ring flash operates off batteries (inside the T Power Control 1 which is mounted to the camera, or a 6 V Power Pack attached to the waist) or the AC Adapter 3. 8. Wide range of applications Together with other modular OM-System components, the ring flash is useful in a wide variety of photographic situations (Recordata Back, Winder, etc.).

Cautions

The ring flash equipment does not feature explosion-free construction. NEVER use it in the presence of flammable gas.
To prevent overheating, do not cover the AC Adapter 3 with a cloth, etc.
Depending on the film used, the Ring Filter POL can cause a slight change in coloration (gold tends to turn out bluish; and red, bright red).
The POL cuts downlight by 3 — 6 stops, so open up the lens aperture accordingly to compensate for the light loss.
